| Abstract: | Three boll shape traits and 5 fiber quality traits of 15 F 1 crosses of upland cotton were analyzed for their genetic variance components and genetic correlation coefficients between pair-wise characters by additive-dominance genetic model with genotype by environment interaction effects. The results indicated that boll shape traits and fiber quality traits were mainly controlled by additive effects and by dominance effects rather significantly as well. The broad and narrow sense heritablity estimates of boll length and ratio of length to width were larger than that of boll width,but all of them arrived at high significant level. The broad and narrow sense heritablity estimates of 5 fiber quality traits also arrived at highly significant level,among which fiber length and strength were more than that of other 3 fiber quality traits. The narrow sense heritablity estimates of boll length and ratio of length to width were relatively high,the additive correlation among the two traits and fiber length and strength were positive and highly significant,indicating that we can improve main fiber quality traits through indirectly selecting boll shape which was easy to manipulate in field selection. In some specified environments,better results might be achieved when ratio of boll length to width was used as indirect selection index in the course of improving fiber quality properties. |
